Pix & ID: Critters that come in your rocks: the good and the bad.

[cloak]

I'm not sure about the first picture, but the second one is of a Hydroid. These things usually just run their course given time so there really nothing to worry about IME.

Spoondude, I think the first two are opisthobranch snails, probably haminoeids. They are most likely algae grazers.

Found a couple of these on my back glass. Can someone tell me what they are please? Sideways pic....sorry :/

 

[bat21]

Not critters, but need help id'ing. What are these white things? They are flat. I've seen them from time to time on my back wall, on my glass, but right now there are tons of them on my rocks. I thought they were snail eggs of some kind. Am I right? If so, what kind? I have turbos, nerites, trochus, ceriths, dwarf ceriths, nessarius.

 

[pagojoe]

Jcook, that's an arminid nudibranch. They feed on soft corals, and that particular one seems to be a common hitchhiker on clove polyps.

Bat21, your white dots are nerite eggs

Cheers,



Don

Yes.

Got a new coral yesterday, a setosa montipora. Acclimated and dipped as usual and after I attached it to a rock I saw this guy. I tried the Lionfish Hitchhiker page but nothing looked quite like it. Should I pull the whole frag out and toss it?

 

[cloak]

It just looks like some type of harmless filter feeder IMO. I'd keep it.

I was hoping I wouldn't have to toss it. It's such a pretty and vibrant coral. Just not sure because it looks a little like a hydroid or something, but they don't usually have feathers on their tentacles right? Kind of sort of looks like a feather duster only really small. For scale, the entire frag is only about an inch.

Can you guys give me a quick verification that this is aiptasia? As for the second one, still no idea what it is.

White goo

White goo

Please help me to ID and recommend a solution for this unknown white goo. It is hard to separate from the rock, kind of looks like boogers when you get it off, and seems to be spreading. I believe it choked out my zoa frag, and I worry it is going to take over the tank if I don't get it eradicated.

Thanks for your help!!

I cant see the aptasia if it is there, can you get a better photo its really blurry? as for the second one, if you are reffering to the red bubble like stuff, it looks like red bubble algae to me. it is a type of macro algae but can become invasive if left to spread.

It's hard to see in that picture, but it doesn't look like aipstasia to me. Maybe a little feather duster

 

[Jdack]

Ya. It's tiny as all. Ok thanks guys!

Hi there, the object in the box i am sure has moved about over a centimetre done the piece of coral. Could anyone help with identifying what it is?
